# The `Employee` table holds all employees including their managers. Every
# employee has an Id, and there is also a column for the manager Id.
# 
#     
#     
#     +----+-------+--------+-----------+
#     | Id | Name  | Salary | ManagerId |
#     +----+-------+--------+-----------+
#     | 1  | Joe   | 70000  | 3         |
#     | 2  | Henry | 80000  | 4         |
#     | 3  | Sam   | 60000  | NULL      |
#     | 4  | Max   | 90000  | NULL      |
#     +----+-------+--------+-----------+
#     
# 
# Given the `Employee` table, write a SQL query that finds out employees who
# earn more than their managers. For the above table, Joe is the only employee
# who earns more than his manager.
